Expand dataset to 4,466 Fajr records across 98 locations (Batch 6)
Added 38 per-date individual DSLR observations from Kassim Bahali et al. (2019) JATMA 7(2):37-48 across 10 new sites: - Sabang, Aceh, Indonesia (5.876°N, 95.340°E) — 11 nights Dec 2017 - Yaring, Pattani, Thailand (6.934°N, 101.319°E) — 2 nights Jan 2018 - Surabaya, East Java, Indonesia — 3 nights Feb 2018 - Sumenep, Madura, Indonesia — 3 nights Feb 2018 - Ternate, North Maluku, Indonesia — 3 nights Mar 2018 - South Sulawesi (Gowa area), Indonesia — 6 nights Mar 2018 - Mersing, Johor, Malaysia — 3 nights Jun 2018 - Kuala Rompin, Pahang, Malaysia — 2 nights Jul 2018 - Nenasi Pekan, Pahang, Malaysia — 2 nights Aug 2018 - Kota Tinggi, Johor, Malaysia — 3 nights Sep 2018 Depression angles computed via PyEphem from actual dawn times + coordinates. Mean D0 range: 17.07° (Pattani) to 19.61° (Kota Tinggi dry season). Includes first Thailand data point (Pattani) and expanded Indonesian coverage. +10 new unique locations (88 → 98)
